AGA Clinical Practice Update on Management of Portal Vein Thrombosis in Patients With Cirrhosis: Expert Review.

BEST PRACTICE ADVICE 11: Portal vein revascularization with transjugular intrahepatic portosystemic shunting may be considered for selected patients with cirrhosis and PVT who have additional indications for transjugular intrahepatic portosystemic shunting, such as those with refractory ascites or variceal bleeding. Portal vein revascularization with transjugular intrahepatic portosystemic shunting may also be considered for transplantation candidates if recanalization can facilitate the technical feasibility of transplantation.

AGA Clinical Practice Update on Screening and Surveillance in Individuals at Increased Risk for Gastric Cancer in the United States: Expert Review.

BEST PRACTICE ADVICE 15: To achieve health equity, a personalized approach should be taken to assess an individual's risk for GC to determine whether screening and surveillance should be pursued. In conjunction, modifiable risk factors for GC should be distinctly addressed, as most of these risk factors disproportionately impact people at high risk for GC and represent health care disparities.

Incidence of hepatobiliary malignancies in primary sclerosing cholangitis: systematic review and meta-analysis.

The incidence of CCA in PSC is substantial, whereas HCC and GBC are rare. PSC-IBD patients may be at higher risk for HCC. These data should be validated in large, prospective studies, and may guide the development of evidence-based surveillance strategies for hepatobiliary malignancies in PSC.

Efficacy and safety of fully covered self-expanding metal stents in the management of Post sphincterotomy bleeding: a Systematic Review and Meta-analysis.

Pooled rates (95% CI) of stent migration were 10% (5%, 20%). In most studies, FCSEMS were used after failure of conventional endoscopic treatments except in two studies, where these were used in some patients for primary treatment, and in others, after failure of conventional endoscopic treatments CONCLUSIONS: Our meta-analysis demonstrates the pooled efficacy and safety of FCSEMS in the management of post-sphincterotomy bleeding especially as a rescue treatment in patients with persistent bleeding after conventional endoscopic treatments.

Delisting From Liver Transplant List for Improvement and Re-compensation Among Decompensated Patients at one-year.

ALD and HBV are most frequent etiologies for delisting due to liver disease improvement. About 10% of delisted patients develop re-compensation, with HBV etiology most likely to recompensate. Models and biomarkers are needed to identify these candidates for optimal use of deceased donor livers.

Post-Transjugular Intrahepatic Portosystemic Shunt Right Atrial Pressure and Left Atrial Volume Index Predict Heart Failure and Mortality: Dual Center Experience.

Increases in right atrial pressure and left atrial volume index post-TIPS, but not CCM status, predict post-TIPS HF and death, respectively. Surveillance echocardiography may play a role in identifying those at highest risk of decompensation post-TIPS. Further prospective study of CCM and its markers in relation with TIPS outcomes is warranted.

Human enteric glia diversity in health and disease: new avenues for the treatment of Hirschsprung disease.

Two major enteric glial classes were identified in the pediatric intestine, highlighting the significant postnatal contribution of Schwann-like enteric glia to glial heterogeneity. Crucially, these glial subtypes persist in aganglionic segments of HSCR patients, offering a new target for their treatment using 5-HT agonists.

In Obesity, Esophagogastric Junction Fat Impairs Esophageal Barrier Function and Dilates Intercellular Spaces via HIF-2α.

We have elucidated molecular mechanisms whereby visceral fat of obese patients can impair esophageal barrier integrity by secreting substances that generate ROS, which activate HIF-2α in esophageal epithelial cells. These mechanisms could render the esophagus of obese individuals vulnerable to damage by acid and other noxious agents.

Prevalence of metabolic dysfunction-associated steatotic liver disease and fibrosis defined by liver elastography in the United States using National Health and Nutrition examination survey 2017-march 2020 and august 2021-august 2023 data.

In the U.S. population, MASLD and fibrosis prevalence are high along with obesity and diabetes. Our findings suggest that early detection of chronic liver disease and targeting lifestyle and other modifiable risk factors may slow disease progression toward advanced fibrosis and cirrhosis.

AI model using CT-based imaging biomarkers to predict hepatocellular carcinoma in patients with chronic hepatitis B.

This AI prediction model, integrating deep learning-based auto-segmentation of CT images, offers improved performance in predicting HCC risk among patients with CHB compared to previous models. Impact and implications The AI-driven HCC prediction model (PLAN-B-DF), employing an automated CT segmentation algorithm, demonstrates a significant improvement in predictive accuracy and risk stratification among patients with CHB. Using a gradient-boosting algorithm and CT metrics such as visceral fat volume and myosteatosis, PLAN-B-DF outperforms previous models based solely on clinical and demographic data. This model not only shows a higher c-index compared to previous models, but also effectively classifies CHB patients into different risk groups. This model uses machine learning to analyze the complex relationships among various risk factors contributing to HCC occurrence, thereby offering more personalized surveillance for CHB patients.

Carvedilol vs. propranolol for the prevention of decompensation and mortality in patients with compensated and decompensated cirrhosis.

Our data endorse the current recommendation favoring the use of carvedilol in the prevention of a first decompensation of cirrhosis and suggest extending the recommendation for its preferential use to patients with decompensated cirrhosis without recurrent or refractory ascites. Impact and implications This study addresses a gap in the comparative effectiveness of classical non-selective beta-blockers (e.g., propranolol and nadolol) versus carvedilol in managing cirrhosis in both compensated and decompensated stages. Our results support the preferential use of carvedilol in both settings due to its superior efficacy in reducing first and further decompensation. However, the retrospective nature of the study and inherent selection biases advise caution against broadly applying these findings to patients with decompensated cirrhosis who exhibit signs of circulatory dysfunction or recurrent/refractory ascites.

Single-cell RNA seq-derived signatures define response patterns to atezolizumab + bevacizumab in advanced hepatocellular carcinoma.

Our study unveils two distinct molecular subsets of clinical benefit to atezolizumab plus bevacizumab in advanced HCC ("Immune-competent" and "Angiogenesis-driven") as well as the main traits of primary resistance to this therapy, thus providing a molecular framework to stratify patients based on clinical outcome and guiding potential strategies to overcome resistance.
